HD audio decoding on older A/V receiver
Dear Forum Members, I will be extremely grateful for some advice regarding my following query.
I have just purchased a Sony BDP-S790 blu-ray player for use with my Sony HTSF2300 amplifier/receiver. I have been hoping to utilise the twin HDMI outputs on the 790 to feed a direct 3D video signal to my TV and send the audio via the second HDMI to the receiver. I have made the neccesary adjustments, such as activating A/V separation in the 790 audio menu settings, and video is working fine. As the HTSF2300 receiver cannot decode DTS HD-MA or Dolby TruHD audio, I was hoping to have the onboard HD audio decoding on the blu-ray player. However, after changing the HDMI audio setting output from "Auto" to "PCM", the sound through the receiver and speakers becomes distorted and muffled (the display on the receiver shows PCM audio). If I change it back to "Auto" , the sound is restored but there does not appear to be any HD decoding. The receiver display in this case shows DTS or Dolby Digital, depending on the format of the blu-ray disc, but this is only decoding the core audio stream and not the HD audio. With my previous blu-ray player (Sony BDP-S760), the display on the receiver would be grayed out, assuming that onboard HD audio decoding was occurring, and the receiver was being used as "pass-through". Also, to allow blu-ray player onboard decoding, should the audio setting be set to "BD-Mix" or "BD-Direct", assuming that this is required? Any advice on this issue would be greatly appreciated. Thank you in advance!
